Bug#952724: "warning: ICC support is not available" warnings

[debian]

Hi,

I've traced the error to the mupdf source. In mupdf-1.18

In source/fitz/colorspace.c:

    #if FZ_ENABLE_ICC
    
    [..]
    
    #else
    
    [..]
    
    void fz_enable_icc(fz_context *ctx)
    {
        fz_warn(ctx, "ICC support is not available");
    }
    
    [..]
    
    #endif

I have no idea of mupdf packaging, but it seems that we could either
compile mupdf with ICC or disable the warning using a patch.

Anybody wants to chip in on this?

Cheers,
Ben
